‘Community’ Cast Releases ‘Save Greendale’ PSA — Pop! Pop! (Video)

"Community" aired its last episode before going on hiatus last night — and it could be its last episode overall, if NBC changes its mind about bringing it back.

The cast for the ratings challenged series released a PSA calling on its small but fierce band of fans to save Greendale Community College — the setting for the show. But they're really talking about the show itself.
